You've defined right here the problem with SUVs. Unless you get one of the car best import models, the ride at 65 on the highway is crap. Now, compared to a suburban, you may consider it good, but I don't consider something that can't do a simple emergency lane change without rolling over a good ride.
The europeans have this amazing comprise vehicle that is called, hmm, lemme think, oh yeah...a station wagon. But then again wagon's aren't cool and SUVs are. Anyway, my rambling point...have you checked out a wagon or some of the newer car/truck cross vehicles?
